enthalpy of reaction मीनिंग इन हिंदी

उदाहरण वाक्य

1. The converse is also true; the standard enthalpy of reaction will be positive for an endothermic reaction.
2. If the standard enthalpy of the products is less than the standard enthalpy of the reactants, the standard enthalpy of reaction will be negative.
3. During his time he taught several undergraduate courses including topics on Mass and Energy Balances, Heat and Mass Transfer, and Enthalpy of reactions.
4. For 2-butanone going to 2-butanol, enthalpy of reaction is-13.75 kcal / mole, which again is in excellent agreement with-14.02 kcal / mole.
5. the standard enthalpy of reaction ? " H " r ?" is related to the standard enthalpy of formation ? " H " f o of the reactants and products by the following equation:
6. The calculation of a heat of a reaction based on difference of bond energies compared to usual enthalpy of formation calculations seems to indicate the necessity of bond energy temperature dependence because the enthalpies of reaction are temperature dependent.
7. For fossil fuels the free enthalpy of reaction is usually only slightly less than the enthalpy of reaction so from equations ( 3 ) and ( 4 ) we can see that the energy efficiency will be correspondingly larger than the energy law efficiency.
8. For fossil fuels the free enthalpy of reaction is usually only slightly less than the enthalpy of reaction so from equations ( 3 ) and ( 4 ) we can see that the energy efficiency will be correspondingly larger than the energy law efficiency.
9. For instance carbon and hydrogen will not directly react to form methane, yet the standard enthalpy of formation for methane is determined to be  " 74.8 kJ mol  " 1 from using other known standard enthalpies of reaction with Hess's law.
10. As determined by the enthalpy's below the corresponding molecules, the enthalpy of reaction for 2-methyl-1-butene going to 2-methyl-butane is-29.07 kcal / mole which is in great agreement with the value calculated from NIST,-28.31 kcal / mole.
